(FR) INTERFEROMETRIE
Abstract: front page image
(EN)An interferometer utilises a short coherence length light source in such a way that the visibility of fringes produced varies as a function of the measurand. In order to provide a signal which represents the value of the measurand, the visibility of the fringes is calculated.
(FR)Un interféromètre utilise une source de lumière de longueur de cohérence courte de sorte que la visibilité de bordures produites varie en fonction du mesurande. Afin de produire un signal représentant la valeur du mesurande, on calcule la visibilité des bordures.
